ConclusionsNonshockable rhythms account for the majority of the cardiac arrests in hospitals in a lower middle income country and are associated with unfavorable outcomes. Future work should be directed to training health care personnel in recognizing early warning signs and implementing appropriate measures in a resource-scarce environment.

AbstractSudden cardiac death (SCD) is due to ventricular tachycardia/fibrillation (VT/VF) and may occur with or without any structural or functional heart disease. The presence of myocardial edema, ischemia and/or fibrosis plays a crucial role in the pathogenesis of VT/VF, irrespective of the pathophysiologic background of the disease. Specifically, in autoimmune rheumatic diseases (ARDs), various entities such as myocardial/vascular inflammation, ischemia and fibrosis may lead to VT/VF. Furthermore, autonomic dysfunction, commonly found in ARDs, may also contribute to SCD in these patients. The only non-invasive, radiatio...

A 69-year-old male with dilated non-ischemic cardiomyopathy and history of sustained monomorphic VT (SMVT) underwent an unsuccessful VT substrate ablation due to the proximity of the earliest activation site to the conduction system. A second attempt was performed using an ablation catheter with mini-electrodes (ME) and multiple extrastimuli to unveil hidden slow conduction (HSC) sites, allowing the performance of a successful ablation. No SMVT was induced thereafter.ME-obtained electrograms permit to accurately localize areas of HSC sites within ventricular tachycardia (VT) substrates.

Authors: Cardoso R, Aryana A, Singh SM, Tandri H, d'Avila A Abstract For over 3 decades, it has been known that reentry circuits for ventricular tachycardia (VT) are not limited to the subendocardial myocardium. Rather, intramural or subepicardial substrates may also give rise to VT, particularly in those with non-ischemic cardiomyopathy. Percutaneous epicardial mapping and ablation has been successfully introduced for the treatment of such subepicardial VT. Herein, we review the indications for epicardial ablation and the identification of epicardial VT by electrocardiographic and imaging modalities. We also discu...

ConclusionsEpicardial origin of VTs arising from the anterior myocardial wall produces a slowing, widening and staircase-shaped notching in the initial VT –QS complex. Thus, the morphology of the initial part of the QS complex in precordial leads can be used as a guide for trans-pericardial ablation of VTs with anterior origin.

This case was written by one of ourgreat Hennepin 2nd year residents, Aaron Robinson, with lots of comments and edits by Smith.Thanks to Dr. Smith and Dr. Travis Olives for being part of this case. A 12 year old girl with a history of mild intermittent asthma presented to the emergency department with worsening shortness of breath over the past couple of days. She is up to date on her vaccinations and has no PMHx besides asthma and a noncontributory family history. She does not identify any specific triggers for her asthma. Initial screen in triage revealed normal vitals signs and a normal temperature. Upon interviewi...
